The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

VASUMATHI BROWN, MD., LADC-1 appears in the CMS NPPES registry as a Addiction (Substance Use Disorder) Counselor provider holding MD., LADC-1 credentials at 49 CENTRAL ST STE UNITB, HOLLISTON, MA, 01746, with a listed phone of (978) 710-9877. NPI 1922045038 was issued on 05/31/2006.

Medicare Part D records for calendar year 2023 show 77 prescription claims written by this provider, covering N/A Medicare beneficiaries and totaling roughly $4K in drug spend. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating.
